Zin Mar Aung says she had never heard of George W. Bush or his wife, Laura, who used her own bully pulpit to push for liberation of Burma's most famous political prisoner, democratic leader Aung San Suu Kyi, then under house arrest.

Suu Kyi is well-known to many now because of the largely unacknowledged work of the Bushes, as well as Hillary Rodham Clinton and John McCain. Since her release, Suu Kyi has risen to public office, accepted her Nobel Peace Prize and been the subject of a movie ("The Lady").

What does all this mean? Start here: Imagine living under a military dictatorship where free speech is punishable by incarceration, torture or worse. Imagine sitting in an 8-by-8-foot cell alone for 11 years with nothing but a small water jug, a "sink" for waste, and a 15-minute daily break for a cold bath. Throw in a lack of amenities (shoes) or even necessities, such as sanitary napkins.

This was Zin Mar Aung's life for 11 years. How did she hang onto her sanity, I asked. She says she accepted that her existence consisted of those 64 square feet and wishing otherwise would do her no good. Meditate on that while keeping in mind that her crime was publicly reading and distributing a collection of revolutionary poems she and her fellow students had written. Zin Mar Aung says she focused on those poems to get her through more than 4,000 days.

What does one do next? How does one navigate freedom in a nation relatively new to democratic reform and find the voice to speak when one has been silenced? Second and third thoughts further crowd the spirit in a country where, despite admiration for The Lady (as everyone refers to Suu Kyi), women are not embraced in the political process.

It takes courage to put one foot in front of the other, much less to become an activist, as Zin Mar Aung and her colleagues have done. Zin Mar Aung picked up where she left off, earning a degree in botany, and now pursuing an international law degree. She established the Yangon School of Political Science and co-founded Rainfall, an organization focused on women's empowerment.

The accomplishments of the four also include helping political prisoners, providing education and training girls and young women vulnerable to trafficking, and advocating for victims of domestic violence. The name of an organization they help suggests the urgency and breadth of their challenges: "Stop Sexual Harassment on the Bus Now."

The three other women are: Hla Hla Yee, a mother, attorney and former political prisoner who counsels marginalized women and provides paralegal training in orphanages and elsewhere; Shunn Lei Swe Yee, who mobilizes young people to work for a more civil society; and Ma Nilar OO, who worked for the International Red Cross for 18 years, advocated for political prisoners and personally provided some of those aforementioned necessities to Zin Mar Aung and Hla Hla Yee when they were imprisoned. More recently, she has been training and finding jobs for at-risk girls and young women (ages 13 to 35). She lost two teens from her program when their parents sold them each for $100. They were of high value, apparently, because they were virgins, the sundering of whom is termed in Burma "to open a new envelope."

Some of these struggles sound familiar, even in our relatively advanced democracy. What is different is the absence of democratic traditions in their country and a lack of the instruments of freedom. Everything — from how to build a feminist movement to how to create a political party — has to be invented from scratch.

What is message? What is public opinion? How does a person get elected? Imagine that. Then meditate about the success of these four brave women.
